Referring particularly to Figs. 1 to 4, one form of wall according to the invention comprises wall members in the form of blocks I arranged in superimposed rows. As best illustrated in Figs. 3

and 4, the blocks, without limitation thereto;

may be hollow and of glass. As shown, the blocks have the oppositely disposed lateral faces 3 in the planes of the vertical sides of the walhand ,have recessed faces 5 extending transversely of the v thickness of the portion ;I5, while the narrower portion of the slot is of width the thickness of the intermediate portion of the element. By moving the two members of Fig. 80, toward each other I those members may be half-jointed by means of wall between the faces 3. As shown, the recesses 5 extend around the four transverse faces of the; 4

blocks so as to present ribs 1 adjacent the faces" 3 extending around the iour t'ransverse sides of 'the blocks, all-the edge's of the blocks 'bein'grounded as indicated at 9. --For convenience the.

surfaces of these roundededges may'be considered as part of the lateral faces 3 of the blocks. It will be understood, however, that the'blocks may be of material other than glass, and need not be hollow, and, if desired, "may be relatively thin transversely, for example, but without lim-v itation thereto, slab-like blocks in which the lateral faces 3 are in the orderof one and one-half inches apart. 1 i

As illustrated, for'holdingthe blocks in assembled relation, transversely extendingmembers I I are positioned at each of the-sets of adjacent transverse edges 9 of the blocks (see Figs. 3 to 6). As shown, themembersI I are of cruciform cross-section, having flattened arms I3 which extendtransversely of the wall between the transverse faces 5 of the blocks. At each of its opposite edges each arm 13 has a thickened portion I5 against which the ribs-1' of the blo'cksrest.

As shown, each of the thickened portions15 is provided with grooves II'of the radial height of the arm opening on the outer edge face'ofthe latter. As best illustrated in Fig, 28, the opposite walls of the grooves are formed with longitudinally extending beads I9-for augmenting the friction with which these walls grip the tongues.

- 2| (Figs. 3, 6 and 30) of horizontally disposed members 23 and vertically disposed members 25, which tongues are driven into those: grooves.

As shown, the members 23and25 are provided at one edge of the longitudinally extending tongue 2| thereof with oppositelyprojecting longitudinally extending flanges 21, theouter edges ofthe flanges being beveled, as indi'catedat 29. (Fig. 30), for engaging-with the surface portions of the rounded edges 9 of the blocks, as shown in Fig. 3. Preferably the horizontally disposed members 23 are long enough to engage with; a plurality of blocks of a row, while the vertically disposed members 25- are of: length corresponding to the height. of theblock, as best shown. in Figs. 1,3,4and6. The transverse members. :II may iconsist of elements cut from long bar-like lengths of metal (see Fig. 22) having thetcross-section indicated in Figs. 8a, 22 and 28. Preferably these members are extruded to the shape indicated, by Fig. 29 to provide at the'opp'osite .edgeportions of the extrusions the flaring portions 3|, after which the margins of thelbar likelengths are subjected to a rolling operation. to cause the portions 3I to approach each other soas to provide the thick the" slots 33, 35 to form the transversely extending member of cruciform cross-section illustratedby Figs. 3, 4, 5 and 6. As illustrated, the thickened portion I5 of each element of Fig. 8a opposite the slot 33 is also provided with a slot 31 of width at least the thickness of the tongue 2I of the members 23fand 25, so that when the elemerits"arehalf-jointed together the thickened portion" I5 of oneelement will not close the groove IT in. the thickened portion I5 of the other element and prevent-reception in the groove of this tongue. .I r Y If desired, the transversely extending members of cruciform cross-section, may be constructed as illustrated by Figs. 10, to 13. As shown in those figures, the arms ofthese members are each. rovided ,with-an'insert 3 9 ofmaterial of poor heat conductivity to prevent conduction of heat by the members from one side to the other of the wall, to which inserts are joined the metallic marginal portions II of the arms. The metal of which the marginal portions are formed may be short lengths cut from long lengths of extruded bar-like members of the cross-section shownbyj theelementsof Figs.l2 and 13. .These bar-like membershave webs 43 at one edge of which is formed the; longitudinally extending thickened portion I5 having the groove I'I, while at its opposite edge .they are provided with a longitudinally extending thickened portion 45- presenting a T-slot 41 having the opening 49.? By slotting one of ,each of ,the elements of; Figs. 12 andsl3, as shown'at 5I,'53 and55, and the others in each case as shown at 51,59 and I 5I,- the two elements'of each figure may be moved toward each other, and bymeansof the slots may be half-jointed to form the marginal portions having the arms 4| of Fig. 10. The inserts of material 39 may be cut from long bars or strips having the cross-section shown in Fig. 10 so as to provide at each edge of the strip a longitudinally extending T-bead 63 for reception in the T-slots of the thickened portions 45 of the marginal portions of the metallic members of Figs. 10 and 11. Insteadof havingseparate transversely extending members II at each of the sets of' adjacent transverse edges 3 of the blocks of the Wall,the construction employed may be that shown by Fig. 22. As there shown, there is provided an elongated member 65, formed ofa long length of the bar-'likeextrusions from which the elements of Fig. 8a are cutshown, this memher 65 is provided at spaced points along the length with the transverse slots 33, 35 and 31, so that elements formed as shown in Fig. 8a may be half-jointed with the member 65 to form the vertical arms |3 projecting. from Opposite sides of the member 65, which arms are spaced apart a distance the length of a block.

The wall may be built up by use of the members according to Fig. 22'by starting with oneof those members at the bottom of the wall and fitting theblocks to it. After a course'of blocks is laid" another of these members may be placed upon the top-of that course and the next course built up on the member so positioned, the operation being repeated until thewall is of the desired height.

As shown in Figs. 3; 4, 7 and 8, the lower vertical arms l3'of' the transversely extending members H at the bottom of the wall are cut away to clear the floor F, and those members are each supported by a'pair of blocksor plates 61. The plates 61, as clearly shown in Fig. 8, areprovided at each end with upstanding lugs or tabs 69 which fit into notches H formedinthetransverse edge portions of the horizontal arms l3. Intermediate its width the plate 61 isformed with a notch 13 which receives the lower vertical arm I 3. In this way the plates Glare locked against movement in a horizontal plane relative to thelower transverse members II. The horizontal arms l3 may be provided with perforations 15 (Fig. 7) through which may extendsuitable fastener members T! (Fig. 3) for securingthe lowermost members H to the floor.

As shown in Figs. 3, 4, 9 and 27, for securing the wall to the ceiling C the bracket members illustrated by Fig. 27 are provided. These bracket members have base portions 19 provided with perforations 8! through which may be passed suitable fasteners 83 (Figs. 3 and 4) for securing the bases to the ceiling. Each base 19 carries spaced downwardly projectingarms 85 at the lower end of which are provided tabs 69 and slots 73 like those on the plates 61- at the bottom of the wall. The horizontal arms I3 at the top of the wall as shown are formed'with notches H the same as the horizontal arms at the bottom of the wall, these notches receiving-the. tabs 69,

veniently, the thickened portions l5 of. the adja' and 31) may be provided for engaging the upper have the tongues 2| and lower flanges 21. like the members 23v and 25. The upper flanges 89 for the members 81 however are thicker, and are provided with'longitudinally extending slots '91. As shown in Fig. 3, the slots 9| of the opposite members 8? receive the lower edge portions of sheet metal members 93 for closing the space between the top of the upper blocks and the ceiling. These members 93,. as shown, are provided with flanges 95 inserted in the cracks 96 between the base 19 and the ceiling, suitable spacer plates 98 being positioned between the bases and the ceiling for forming the cracks. The members 93 preferably have sufficient resiliency to permit of the wall may be employed atthe bottom of the wall. Further, if desired, the plates 61 at the.

bottom of the wallmay be of greater height than,

as shown, so as to hold the lower course of blocks well above the floor.

In either case sheet metalv members similar to the members 93 at the top of the wall may be secured to the opposite members 81 at the bottom of the wall and to the floor to close the space thereat, the: members 93 in. such case serving-as base-boards, and the. construc tion providing a. conduit beneath the wall. for Wiring and the like- I Where the wall according to the invention abuts with the wallpost, or; other vertically disposed portion of' the building the adjacent horizontal arms I3 may abut with the surface of thatpo'rtion, as. shown in Figs; 25. and 26, and each of the verticaliarms l'3 may be perforated and secured to such; porton by suitable fastenersQ'L i As will be obvious, any spaceatthe top, bottom or edges of the wall,- or elsewhere between the wall and a fixed part of the building, may, if desired, be groutedwith cement or, the, like to close'the space: between. the walland that part. Where the wall has a blank end, as indicated at the right handside ofFigs. 1 and 14, the adj a-. 1

cent vertical block engaging. members 25- may maybe provided at each'side with notches 99 (Figs. 14 and 23). Into these notches may be snapped the longitudinally extending beads l0! projecting inwardly from the flanges I03- of the cover members having the. webs I05, the webs H15 of these cover members having 1 sufficient resiliency to permit this action.

Where two lengthsof wall A and Bintersect, as shown at the upper left hand corner of Fig.,2, the construction may be as shown in Figs. 18 to 20. Referring to these last mentioned figures, conveniently a rigidly secured post' i0! is placed in the space bounded by the four planes of the sides of-thetwo wall lengths, andeach adjacent members I I of the wall length A forming the ,base' of the intersection may be secured to the post by means of suitable brackets I09. Concent horizontal arms of the transversely extending members H of the wall length Bare cut away, as indicated by the notches Ill (Fig, 18),

and the corner portions of the notched arms are inserted in thegrooves H in the thickened portions Id of the adjacent horizontal arms of the members ll of the wall length A. In this way assurance is had that the upper and lower edges of the blocks of all the three wall sections abutting with thepost will be in alignment, and one length of wall will be secured to the-other.

For further securing these intersecting lengths of wallto each other the adjacent horizontal arms of the wall length B may also be secured to the post by brackets H3.

The vertical members 25 at the intersection of height of the wall, the edge portions of the plates being received in the slots 9| of the members 81.

As shown in Figs. 18 and 20, and also in Fig. 6, members I I1, cut-from the lengths from which the arm portions l3-of the transverse members U are cut, may be placed intermediate the lengths of blocks for further tying together the horizontal wall engaging members 23, or, if de sired, the vertical wall engaging members '25.

The framing for a corner of the wall maybe as shown in Figs. 16 and 17. As illustrated, a rigidly secured vertical post H9 is placed at the corner of the wall between the, planes of the opposite side faces of the wall. The horizontal arms I3 of the transversely extending members II adjacent the post are, as shown, shortened, and abut with the post, and the vertical arms I3 are secured to the post by means of suitable fasteners I2I. The lengths of these shortened arms I3 preferably are such as to permit the adjacent members 25, which preferably extend substantially the full height of the wall, to abut with each other, as shown in Fig; 16.

As shown, at one side of the post H9, just referred to, are secured transversely extending members I I for supporting an adjacent vertically extending member I23, more fully illustrated in Fig. 32, and horizontally positioned members 81 at the top and bottom of the wall. As shown, the member I23 has a tongue 2I for reception in the grooves I1 of the verticalarms I3, which tongue at one edge'tl'iereof carries oppositely projecting flanges I25, each of which is provided with one of the grooves or slots 9|. Supported by this member I23 and the adjacent vertical member 81 on the same face of the wall is a cover panel I21. Supported by the same member I23 and the adjacent vertical member 81 on the outer face of the other section of the wall is a bent cover plate or panel I29. The lower and upper edges of the panels I21 and I29 are supported by the members 81 at the top and bottom of the wall. The panels I21 and I29 preferably are of resilient sheet metal, and finish the adjacent portions of the wall.

Where a long length of wall needs bracing, suitable posts I3I may .be placed along its length, as indicated in Figs. 1, 2, 14 and 15. The trans- The flanges I45, each of which is provided with longitudinally extending slots I41, as shown are provided on their opposite sides with longitudinally extending flanges I49 for engaging those 1 sides of the posts I33 and transverse member I35 which are opposite the web I39 of the section, the latter being secured to these posts and member by suitable fasteners II. As shown, the spaces atopposite sides of the posts I33 adjacent ii the plane of the wall are closed by resilient sheet metal panels I53 respectively carried at opposite edge portions thereof by insertion of those portions in the slots I41 and 9I of the adjacent versely extending members II at opposite sides of these posts may be secured thereto and the spaces between those members covered by use of the block engaging members 81 and panels I21, as described in connection with Figs. 16 and 1'1.

Where the wall has a door opening D (Figs. 1 and 21) suitably secured vertical posts I33 extending from the floor F to the ceiling C may be placed at each side of that opening, as indicated in Figs. 1, 14, 15 and 21. Above the opening may be placed a transverse member I35, of the same cross-section as the posts I33, to which latter opposite ends of the transverse member may be secured in any suitable way, say by welding. The section of the wall above the door opening as shown is supported on the transverse member I35, as will be clear from Figs. 1 and 21. The horizontal arms I3 of the wall sections at opposite sides of the door opening preferably abut with the posts I33, but preferably-are not secured thereto, so that jars imparted by slamming the door will not be transmitted to those sections;

The door jamb sections, indicated in their entirety at I31 (Figs. 1 and 14), are conveniently lengths cut from elongated members preferably formed as extrusions. These sections; which preferably are mitered' at the corners of the door flanges I45 and members 81.

The block engaging members 23, 25 of Figs. 1 to 6 and-30 may also be employed with blocks I55 of the type shown in Figs. 33 and 34. These blocks have the lateral faces I51, each of which faces about its four edge portions is recessed to provide narrow surfaces I59 connected to the intermediate portion of the face by curved surfaces I6I (Fig. 34), the four transverse faces I63 of the block being substantially flat. When the tongues 2| of the members 23 or 25 are driven into the grooves I1 of the arms I3 either or both the surfaces I59 and IBI will be contacted by the flanges 21 of those members, or only the edges I65 of those flanges will contact with the surfaces IBI, depending upon the particular shape of the edge portions of the block.

When blocks I61 of the type shown in Figs. 35, 36 and 37 are employed, the construction is preferably as shown in those figures. Each lateral face I69 of the blocks illustrated is deeply recessed about its four edges to provide surfaces I1I connected to the intermediate portion of the lateral face by curved surfaces I13, the four transverse surfaces I15 of the block being substantially flat. These transverse surfaces rest upon the thickened portions I5 of the arms I3. Driven into the grooves'I1 of the arms are the longitudinally extending tongues I11 of members I19. As shown, these tongues at their outer edges have oppositely projecting longitudinally extending flanges I8I, the latter at their outer edges having the portions or flanges I83 parallel with the tongue I11 to provide grooves I85, the

outer sides of the flanges I83 being recessed as shown at I81. When the tongues I11 are driven into the grooves I1 the surfaces of the recesses I81 on the flanges I33 will contact with the surfaces I13 of'the blocks, the surfaces of the recesses I81 preferably having a shape adapting them to fit said surfaces I13, and the portions of the thickened parts I5 of the arms I3 at opposite sides of the grooves I1 thereof enter the grooves I85 of the members I19. The construction is such that, if the blocks are misshapen to such an extent as to prevent the surfaces of the recesses I81 of the members I19 from contacting with the surfaces. I13 of the blocks, the end surfaces I89 of the flanges I83 will contact with the surfaces I1I of the blocks. As will be clear from Figs. 37 and 39, the outer edge of each of the arms I3 of the transversely extending members is notched adjacent the portions I5 of the other arms, as'shown at I9I, so that the flanges I83 of the members I19 may clear those portions.

According to the modification illustrated by Figs. 40 to 43, the arms I3 of the transversely extendingmembers are formed with spaced raised beads I93 at each of opposite sides thereof intermediate the thickened portions I5. The outer edges I95 of these beads lie beyond the planes of the lateral surfaces of the thickened portions are being placed .the

:aaaaoe if placed in the spaces Zil'l between the blocks and the arms 13. I

The beads I93 are preferably iformedtintegrally with the arms f 3,;and conveniently maybe in the form .of longitudinally extending members on the elongated bars. from which :the arms 'are' out,

which bars, as hereinbefore mentioned, are preferably formed by extrusion.

For further securing the flanges 25 of the horizontal caps 23 in the grooves I! of the arms 3 of the transversely extending members of crucithe blocksias they mentioned members from each ,groove at the end of each member 'to that of an adjacent member for tying ,said memberstogether. I

Although the construction just described is illustrated in connection with the cru ciform members according to Figs. to 42, it will be understood that the same construction may be employed with the other modifications of the cruciform members hereinbefore described.

It will be understood that, within the scope of the appended claims, wide deviations may be made from the forms of the invention shown without departing from the spirit of the invention. 1
